Map not updating when adding a new layer

[bonnojold]

Using mapsui with Xamarin for Android/iOS I came across the problem that the map does not update when adding/removing layers, nor do I seem to find a solution to update it manually.

I'm having a custom class which inherits from the ITileSource interface, the layer is not shown until I zoom/pan the map.

Do you use the latest source or the NuGet package?
In the latest source there are two map control for both Android and iOS. On Android MapControl is new and MapView is old. On iOS MapControl is new and MapControlUIKit is old (the MapControl in the nuget package was later renamed to MapControlUIKit).

Using NuGet package 0.2.27 which seems to be the latest

In android I use Mapsui.UI.Android.MapView
In iOS I use Mapsui.UI.iOS.MapControl

Should I update to source?

That will not solve the problem. This needs to be fixed by calling ViewChanged in Map.LayersLayerAdded.

A workaround is to call MapControl(or MapView).Map.ViewChanged(true) after you add the layer. I think the nuget version still needs an extra extent and resolution parameter. You could use the Map.Viewport's extent and resolution for that.

I was convinced I already tried the ViewChanged method so I kept looking for other solutions. Easy fix, thanks!
